My latest blog post: Reverse Engineering a Broken Night Light - Part 1 - Tear Down
https://mikecoats.com/night-light-part-1/
We bought our first Night Light when our daughter was born; within 3 years, it and its replacement had broken. Let's tear it down, reverse-engineer what's left, and build it back up with some extra 'smart' features.
Computer engineer interested on #cybersecurity and #reverseengineering looking for job.
Maybe I do not have the skills, but one thing i can say is that I’m pretty good on getting my shit done, even if is something new to me.

1/X Unboxing the #MSM8916 based M9S-E LCD Modem WiFi ("5G", but not really)
After the huge success of Debian on the #OpenStick LTE USB dongle three years ago, I wondered if you can still get MSM8916-based LTE routers to run Debian on. The search results on AliExpress piqued me: there is a new 17€ device with a color LCD screen!
Fast forward two weeks, it's here. Fasten your seatbelts to see how it works (and how it doesn't).
A question for the #retrocomputing #reverseengineering crowd: Is there any prior work on low-level details of how the 8051 CPU core functions? Down to gate/transistor level.
Atlassian announced their CLI agent 2 days ago…

…and it's already been reversed engineered by AI tools.

The result is a clean‐room specification, a non-derivative reference implementation. I.e., no copyright protection.
LLMs not only will end human developers, they'll end any proprietary software.
My latest blog post: I presented at the 2025 Open Hardware Summit
https://mikecoats.com/presented-at-ohs-2025/
Apologies for the break in blogging, but I've spent the past month preparing for, and then giving, my 'VanSpoof and F**dG3ar' talk at the 2025 Open Hardware Summit.
Been here a while and haven’t found #hardware #hackers or those #building projects. Where’s the #bugbounty pros with the tips? #Blueteam with those new #YARA rules?
Here’s a $20 FPV scanner I’ll probably document and open source.

OSIRIS, the student-run #cybersecurity research lab at NYU, is seeking #challenge writers for our upcoming CSAW #CTF later this year! (For those who don't know CSAW, it's one of the largest student-run #cybersec events in the world: https://csaw.io ) Web, #ReverseEngineering, #pwn, and #cryptography challenges are prioritized, and all experience levels welcome. Interested? Shoot me a DM or email osiris@osiris.cyber.nyu.edu.
In the demo version of Cryo's Dune, Feyd-Rautha Harkonnen was based on a production image of Sting from the Dune movie, but was redesigned before release.
Here's a video of the image of Sting, Feyd-Rautha from the demo version, and the final portrait from the game.
(Let's see how Mastodon handles a very wide video…)
About time we get this #nakeddiefriday going, friends.
Today's exhibit is one ST1305B, by ST Micro. This is a memory card IC with 192 bits of memory on the die.
The die itself is only 1.40×1.18 mm, quite on the small side.

A short thread follows.
Crazy thought… what if your decompiled Objective-C code looked like Objective-C code?
Today's journey: implementing an Objective-C “pseudo-language” view for Binary Ninja.

+Fravia passed away on a Sunday, the 3rd of May, 16yrs ago.
Even after all this time, I keep meeting people who tell me how influential he's been for them. People I immediately feel connected to, as if we were meeting through his website once again.
I wonder what he would say today, after witnessing the enshittified Web. What I am sure about, he'd have a lot of fun learning (and teaching) how to break out of all this.
My latest blog post: I'm presenting at the 2025 Open Hardware Summit
https://mikecoats.com/presenting-at-ohs-2025-cta/
I'm excited to announce that in one month's time I'm presenting at @oshwassociation's Open Hardware Summit 2025. My talk's titled "VanSpoof and F**dG3ar: Reverse engineering proprietary bike components to prevent e-waste" and covers everything involved in designing replacement, open source, parts to repair VanMoof e-bikes.
Let's get this #nakeddiefriday started, people!
The guest of today is one TMS70C42A by TI. It is a 8-bit MCU carrying 4KB of ROM and 256B of RAM, with three timers and a UART.
This particular die was bit by gremlins, and a small part of it is missing; nothing crucial though. Let's have a walk around.

“The invalid 68030 instruction that accidentally allowed the Mac Classic II to successfully boot up”
"This is the story of how Apple made a mistake in the ROM of the Macintosh Classic II that probably should have prevented it from booting, but instead, miraculously, its Motorola MC68030 CPU accidentally prevented a crash and saved the day by executing an undefined instruction.”
Hello! 
I don't want to #GetFediHired (yet?), but I am looking for contacts 
who can help me connect and offer a reality check on a potential new career path 
by telling about their experiences.
I'm currently working as an embedded software engineer 
, but I'm exploring a transition into IT/OT security — ideally working as a pentester or reverse engineer focusing on embedded devices, IoT, or SCADA systems 
.

My latest blog post: VanSpoof v1.0
https://mikecoats.com/van-spoof-v1-0/
I'm happy to announce the v1.0 release of VanSpoof. My VanMoof X3 now starts up, without an e-shifter connected, and does not show an Error 44 status! The bike thinks it's connected to a working, functional, e-shifter!
Today we broke 12k stars on #GitHub remaining #1 on Reverse Engineering there and #1 for, “Reverse Engineering Tutorial” on Google. Thanks again for all of your continued support to help get new folks free training on #ReverseEngineering for everyone! https://github.com/mytechnotalent/Reverse-Engineering
